You can only configure digit manipulation to occur at the route list and route pattern levels. This is why you should group similar devices together in the same route group: All devices in the route group will have the same digit manipulation settings applied.

A

After a device has been assigned to a route group, it is made unavailable to any other configurations. If you want to use a device for multiple route patterns, associate its route group with multiple route lists. You can only associate devices directly with route patterns if you are not already using those devices in a route group.

C

Voice gateways are used to bridge VoIP networks to either non-VoIP networks (such as the PSTN) or to other VoIP networks.

5.

A

Route groups contain a list of gateways to use in precedence order.

6.

B, C, and D

The ! wildcard represents a variable-length string, the . wildcard represents a single digit, and the @ wildcard represents the entire NANP. The * is not a wildcard as it represents just the * digit on a telephone keypad.

7.

C

Route lists contain an ordered list of route groups that CallManager should use when it matches a route pattern.

8.

E

When digits are contained within braces, they match only a single digit in the extension. In this case, [45] could be read in plain English as, "Four or Five" (mentally insert a comma between the digits).

9.

B

To stop the secondary dial tone, you need to remove the check from the Provide Outside Dial-Tone check box for the route pattern. It is checked by default when the route pattern is created.

10.

C and D

The X wildcard matches any dialed digit, whereas the ! wildcard matches any variable-length dial string (zero digits or more). By placing the 7XX before the !, the CallManager expects to see at least three dialed digits followed by any number of digits.
